水稻旱地育秧在我国有着悠久的历史,双季晚稻旱地育秧已普遍采用。但双季早稻采用旱地育秧尚少。我们在1992年在湖南对早稻旱地育秧与湿润育秧作了对比试验。旱地育秧于3月15日播种,即连续遇到12天的日最低温3—4℃、最高温8—9℃的阴雨天气。湿润育秧于3月28日播种,二种方法育秧均覆薄膜。试验结果如下:
Rice paddy cultivation in our country has a long history, double cropland rice cultivation has been widely used in dry land. However, double-season early rice is still less dryland seedlings. We conducted a comparative experiment in Hunan in 1992 on wetting seedlings and wetting seedlings for dry land in early rice. Dry seedlings planted on March 15, that is, the continuous encounter 12 days daily minimum temperature of 3-4 ℃, the highest temperature of 8-9 ℃ rainy weather. Moisture seedlings planted on March 28, the two methods are covered with thin film seedlings. The test results are as follows:
